question 2-4 Subtitle Paragraph Cardiovascular Physiology Poiseuille's Equation Practice Sheet a panelowinge nquested nformation a. Initial pressure 80 mmHg b. End pressure= 0 mmHg c. Vessel length 250 mm d. Viscosity 3 e. Vessel radius 1.5 mm 2. Calculate the resistance the vessel has (label will be mmHg min/L) Using the data above, what is the new vascular Resistance if the radius changes to 2.75 mm? 3. Using the same data from question #1, length becomes 32 mm? 4 what happens to the Resistance if the vessel

Explanation / Answer

3) The equation which is used to calculate the resistance of vessel wall is given by Hagen - Poiseuille's equation

DeltaP = (8MuLQ)/(Pi R 4 )

Where deltaP is pressure difference

Mu is viscosity

L is length of the vessel

Q is the flow rate

R is the radius of the vessel
